STOVE- G RAT E.

SPECIFICATION-forming part of Letters Patent No. 423,721, dated March18, 1890.

Application filed November 21, 1889.

To all whom, it may concern:

Be it known that I, CHARLEsL. BnERs, of Scranton, in the county ofLackawanna, in

``the State of Pennsylvania,'have invented new ing either the lire-bricklining` or Water-back or Water-front or, in fact, any portion of theWalls of the lire-box above the grate; and the object of the inventionis also to provide a rotative grate, which shall be eliicientin itsoperation and adapted to be left at any point of its rotation withoutimpairin g its eliiciency and to that end the invention consists in thenovel construction and combination of parts hereinafter fully described,and specifically set forth in the claims.

In the annexeddrawings, Figure l is a top plan view of a grate embodyingmy invention, a portion of the frame being broken away to illustrate thearrangement ofthe removable journal of the grate-bar. Fig. 2 is averticallongitudinal section on line Fig.`l. Fig. 3 is a verticaltransverse sectionon line y y, Fig. l. Fig. 4. isla transverse sectionof one of the grate-bars taken on line e' a, Fig.

2. Fig. 5 is a side elevation of one of the grate-bar sections. Fig. 6is a detached perspective view of the shaft of the grate-bar. Figs. 7and 8 are detached side views of the journal Without and with thegear-Wheel. Fig. 9 is a detached perspective View of the ,catch orlocking-bar by which the journals are retained in the frame, and Fig. l0is a side ele vation of one of the gear-Wheels of the grate.

Similar letters of reference indicate corresponding parts.

A denotes the supporting-frame of the grate, which frame may be of anysuitable form for supporting either a brick lining or a Wate back orfront above the grate.v

C C represent rotative'or rocking gratebars,

Serial No. 331,111. (No model.)

the axial supports of which I make separate and detachable from the`grate-bars and seat them in the frame A, so as to be also detachablefrom the latter or movable longitudinally therein or to and from thegrate-bars in any suitable manner. I preferably, however, employ forsaid axial supports journals a and a', both of Which are detachable fromopposite ends of the grate-bar.

, The journal a, which supports lone end yof the grate-bar, is extendedthrough a compartment A formed across one end of the frame A, as shownin Fig. l of the drawings, and is pivoted in the Walls of saidcompartment, and projects from the inner side of the frame Asufficiently to receive the end of the grate-bar C, which I preferablyconnect to said journal by a polygonal lug b on the end of the gratebarentering a corresponding polygonal socket c in the inner end of thejournal, and thus compelling the grate-bar to turn with the journal. Toprevent longitudinal movement of the said journal, and thus maintain thesame. in its connection with the grate-banl form the journal with acircumferential groove ol or shoulder d and insert in said groove orplace against the shoulder a suitable catch, which I prefer to form of aplate P, placed across an opening ein the bottom of the compartment Aand provided with a tongue f, Which enters the groove d and abutsagainst the shoulder d', said plate being detachably secured to theframe A bya lug g, projecting from the frame and through an aperture inthe plate and having a key g passing through its protruding end, asshown in Fig.42 of the drawings.

To protect the protruding inner end of the journal a, I formthe Wall ofthe frame A with an inward-projecting shieldY h, Which covers the saidjournal. The journal d on the opposite end of the grate-bar is removableinward from the frame A, and is formed with a collar h', by which itabuts against the inner side of the frame. The shank of this journal isformed With a square or polygonal portion a, on Which is mounted agearwheel i, meshing with aj corresponding gear-Wheel on the companiongrate-bar. Said gear-Wheelis pro- IOO vided with a square or polygonaleye, by

which it is seated on the polygonal portion of the journal=shank and isremovable endwise from the same, and is retained thereon by 'guards Z Zon the frame A at opposite sides of the gear-Wheel.

The grate-bar I form of a polygonal shaft s and blocks or sections I II, which latter are formed separate from each other and each oftriangular shape in its vertical plane and provided With a centralpolygonal eye o, by which it is detachably mounted on the aforesaidshaft, the alternate sections\having said eye disposed with its anglesin the same positions in relation to the teeth t t t of the 'respectiveYsections, and the intermediate sections having the eye o disposed withits angles in positions relatively midway between the angles of the eyesof the aforesaid alternate sections, so that each section stands withits teeth t tt at angles intermediate of those of the adjacent sections,as illustrated in drawings.

In some cases only one of the described grate-bars may be employed; butin the majority of cases a plurality of said bars are required, andconsequently in the vlatter case a corresponding plurality of journalsct a will be seatedy removably in the frame A.

The grate-bar. is readily removed from the supporting-frame A by firstremoving the catch or plate P and then drawing the journal d outwardfrom the frame sufficiently to.

release said journal from the grate-bar.

Having described my invention,whatI claim as new, and desire to secureby Letters Patent,

IS-f

l. The combination, with the frame, of ya journal seated movablylongitudinally in the frame 'and provided with a circumferential grooveor shoulder, the gratebar detachably his connected to the inner end ofsaid journal, and a plate detachably connected to the frame and providedwith a tongue entering. the groove of the journal, substantially as setforth and shown.

V2. The combination of the frame formed with a'compartment across itsend and with an opening through the bottom of said compartment, aljournal extending transversely through said compartment and seatedremovably in the frame and formed with a ci r- Fig. 4 of theAcumferential groove in the compartment, a plate detachably connected tothe frame and closing the aforesaid opening and provided with a tongueentering the groove of the journal, andthe grate-bar detachablyconnected to the inner end of the journal, substantially as describedand shown.

3. In combination with the frame, a plurality of journals seated movablylongitudinally in the frame and provided on their inner ends withcollars abutting against the inner side of the frame and formed withpolygonal shank portions, intermeshing gears seated on said shankportions and removable n endwise therefrom, guards on the frame atopposite sides of said gears, and grate-bars detachably connected to theinnerl ends of the journals, as set forth and shown.

4. In combination with the frame, two sets of journals seated 'movablylongitudinally in opposite ends of the frame and provided in 5. Theimproved grate-bar composed of the polygonalshaft s, and the sections III, formed separate from each other, and each of said sections oftriangular shape in its vertical plane and mounted removably on theaforesaid shaft, and disposed with its teeth t t t at anglesintermediate of those of the adjacent section, substantially asdescribed and shown. In testimony whereof I have hereunto signed my nameand afliXed my seal this 19th day of November, 1889.
